GS: 13 | GP: 15 | Snaps: 469 Season in review: The Ravens signed this massive veteran to potentially back up 2010 second-round pick Terrence Cody. But Kemoeatu didn't just make the team; he wrestled the starting job away when Cody struggled in training camp. Kemoeatu started all four playoff games and won a Super Bowl title, a remarkable story given his road back to the Ravens, but nose tackle was arguably the team's weakest spot. Signature moment: In the epic double-overtime win in Denver, he played 42 snaps, one of his heaviest workloads of 2012, and played very well as the Ravens shut down the Broncos running game in the win. Stat that stands out: 122.8 -- rushing yards allowed per game by the Ravens defense, 20th in the NFL. Pro Football Focus grade: -5.7 overall | -1.4 against the run | -7.2 as a pass rusher | +0.5 in pass coverage. Outlook for 2013 and beyond: Ravens general manager Ozzie Newsome said last month that the team needs to get stronger up the middle on defense, and that starts at nose tackle. Cody probably isn't going anywhere, so the Ravens will likely let Kemoeatu walk in free agency and look for a new starter in the draft.
